Authenticate with your GHL API credentials and include the required scope (contacts.readonly) to securely access contact data.
In Zapier, configure an OAuth flow or API key to authorize the app. Access tokens are stored securely and reused for requests.
GET /contacts/:contactId — Retrieve a single contact; GET /contacts/:contactId/tasks — Retrieve tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/notes — Retrieve notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a specific note; GET /contacts/:contactId/appointments — Retrieve appointments for a contact; GET /contacts/ — Retrieve all contacts; GET /contacts/business/:businessId — Retrieve contacts for a business; permissions: contacts.write; POST /contacts/ — Create a contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark task as completed; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Tag a contact.
Trigger on new or updated tasks for a contact to start workflows.
Actions include creating or updating tasks and tagging the contact to reflect changes.
Example methods: GET /contacts/:contactId/tasks to read tasks; POST /contacts/:contactId/tasks to create a new task.
Key fields: contactId, taskId, taskName, status, dueDate.
Trigger when a note is added or updated for a contact.
Actions include creating or updating notes and associating them with the contact.
GET /contacts/:contactId/notes; POST /contacts/:contactId/notes
noteId, content, createdAt, noteType
Trigger on appointment creation or updates.
Actions include creating, updating appointments, and sending reminders.
GET /contacts/:contactId/appointments; POST /contacts/:contactId/appointments
appointmentId, dateTime, status, location
Real-time data access across apps without writing code.
Automations across tools without a developer.
Secure, scoped access with predefined permissions and a scalable workflow.
This section defines the API elements you’ll use: endpoints, authentication, triggers, actions, and how data maps between Contacts API and Zapier App Connector.
A defined set of endpoints that enable programmatic access to data and actions.
A specific URL path that corresponds to a particular API operation.
An authorization framework that allows secure access to user data without sharing passwords.
An access-level constraint that determines which data and actions are allowed.
Trigger on contact changes to push updates to CRM, email, or task apps.
Generate tasks automatically when notes are added.
Schedule reminders and calendar events when appointments are set.
In Zapier, start a new connection and select the Contacts API resource.
Enter your GHL credentials and set the scope to contacts.readonly (or the required permission).
Run test requests against endpoints to verify data flow, then enable the connection.
GHL supports OAuth 2.0 for secure authentication in the Zapier App Connector. Use OAuth 2.0 to authorize the integration and obtain an access token. If your setup uses an API key, ensure it is kept secure and used only in server-to-server flows; Zapier handles token refresh automatically.
The available endpoints include retrieving contacts, tasks, notes, and appointments. Read-only access is provided by the contacts.readonly scope; to write you need appropriate permissions such as contacts.write. Use the endpoints to fetch data for automations and map fields to destination apps.
Yes, write operations require appropriate permissions (e.g., POST /contacts/, PUT /contacts/:contactId). If you only need read access, keep the scope limited to contacts.readonly to protect data. Enable write access only when necessary.
In Zapier, run a test of the trigger and action steps using sample data. Verify responses, map fields, and confirm data flow between systems. If issues arise, check credentials, scopes, and endpoint paths, then re-run tests.
Scope defines what data and actions the integration can perform. For example, contacts.readonly allows reading data, while contacts.write permits creating and updating records. Always minimize scope to the necessary level to reduce risk.
If you need endpoints not listed, you can request access or explore alternative methods within the API. Many common operations are available; contact support if additional capabilities are required beyond the standard REST set.
Endpoint references and field mappings are documented in the GHL API guide and the Zapier App Connector docs. Use these resources to align fields across apps and maintain a consistent data schema.
Due to high volume, we will be upgrading our server soon!
